On the latest episode of “Blindspot,” Jane (Jaimie Alexander) learns about the dark web.

In Zap2it’s exclusive sneak peek, it begins with a new app that Patterson (Ashley Johnson) hasn’t even heard of called “Trakzer.”

Trakzer “hacks into the GPS signals from Blue Force trackers on government vehicles and maps their exact location.” And the owl logo for Trakzer is tattooed on Jane’s leg.

“Every single government agent is now a potential target, including us,” Agent Weller (Sullivan Stapleton) says ominously.

In “Cede Your Soul,” the FBI team msut work with the app’s “surprising creator” to take down the technology before it leads to another assassination.

“Blindspot” airs Mondays at 10 p.m. ET/PT on NBC.
